This program <br />uses a local weather data file and calculates the hourly performance of the system based on the angle of <br />insolation, the air temperature, the wind speed, the intensity of clouds, and so on. The hourly PV output is <br />subtracted from the hourly electric load profile data from SCE to determine the hourly energy use with PV in <br />place. The electric bill is calculated based on how these kWh fall into the On -Peak, Part -Peak, and other bins to <br />calculate 12 monthly bills for the site with and without solar. <br />The annual bill savings are included with the system capital cost to evaluate the lifecycle vale of the project and <br />its energy savings. The parameters included in this analysis are listed in the Appendices. The following table <br />summarizes the outcomes of the financial evaluation. <br />The sum of all the solar projects has a positive net -benefit over 25 years. However, it is only the Garthe Station <br />and the West Station that have positive net -benefits as individual sites. Further, it is only the West Station that <br />has a significantly positive net -benefit. <br />The following figures show the preliminary solar layouts at each site, with some initial commentary on some of <br />the challenges that might arise with each design. <br />II}} it 26 — 84 2�/7/20 <br />CI"'� OII::: Ak V Newcoirrib I eirson I ��eainnii& <br />PREVIEW Date: Nov 03, 2021 Workspace ID: WS00800354 Funding Opportunity Number: R22AS00023 <br />
